Nvidia Titan X vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which comes with a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also features 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800, in theory, should perform a small bit faster than the Nvidia Titan X overall. (explain)

Radeon RX 6800		524288 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 32768 (7%)

Texel Rate

The Radeon RX 6800 will be quite a bit (approximately 29%) faster with regards to AF than the Nvidia Titan X. (explain)

Radeon RX 6800		408000 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 90592 (29%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 6800		163200 Mpixels/sec
Nvidia Titan X		136032 Mpixels/sec
	Difference: 27168 (20%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
